Designer and Author George Lois once said "You can be Cautious or you can be Creative (but there's no such thing as a Cautious Creative)." Basically, you can never innovate without taking a little risk. If you're being truly creative, there's always a chance your fresh idea will flop, or won't be doable, or otherwise won't succeed. If you're working on something that's a guaranteed success, it's unlikely you're creating anything new and different. If you really want to create something new, brace yourself and grow those wings on the way down the cliff.
